Objective To investigate the expression of RCAS1,which is a receptor-binding cancer antigen expressed on SiSo cells in many tumor cell lines. Methods Using real-time polymerase chain reaction(PCR),Northern blot,immunohistochemical examination and enzyme-linked immunosorbent assay,we detected the expre-(ssion) of RCAS1 in 10 different tumor cell lines and two normal cell lines. Results The expression of RCAS1 in the tumor cell lines and the fetal renal cell line(293 cell) was detected by real-time PCR and Northern blot,but not in the normal liver cell line(LO2 cell).The results of immunohistochemical examination on the tumor cell lines and the 293 cell showed that RCAS1 existed in cytoplasma and on cell surface.Except HuH-7 cell and LO2 cell,the soluble RCAS1 protein in supernatants of the other cells was significantly more than that in DMEM(P

Vascular Endothelial Growth Factor and its receptors may be the pivotal stimulants in the process of growth and metastasis of a neoplasm. They boost the genesis of the blood vessels of brain glioma. Their expression is correlated with the grading of glioma. They are ideal targets in the treatment of inhibiting the growth of the blood vessels of brain glioma.

AIM: Using surface active agent that has wetting ability and solubilising to increase the extraction rate of curcumin. METHODS: Different surface active agents, such as span, span 60, tween 20, tween 85. SDS and CSBS, were added and then the curcumin was determined. RESULTS: When we added 0.5% sodium dodecyl sulfate (SDS), it could increase the extractive rate of curcumin by 16%. CONCLUSION: Different surface active agents have variable solubiitzation of different drugs. SDS can affect the extractive rate of curcumin.

Objective To study the effects of Duliang capsule on the expression of calcitonin gene‐related peptide(CGRP) and cholecystokinin(CCK) in the midbrain of a rat migraine model ,and explored treatment effects and mechanisms of Duliang cap‐sule on rats with migraine .Methods A total of 24 rats were randomly divided into four groups :normal control groups(A) ,migraine model groups(B) ,Duliang capsule control groups(C) and Duliang capsule treatment groups(D) .C and D were intragastrically per‐fused with Duliang capsule(0 .5 g · kg -1 · d-1 ) .After 7 days ,nitroglycerin was subcutaneously injected into the buttocks of the B and D to induce migraine .Two hours after nitroglycerin injection ,the midbrain were isolated CGRP and CCK expression in midbrain were determined using SYBR Green I real‐time quantitative PCR .Results CGRP mRNA expression was significantly lower in mid‐brains of rats in the Duliang capsule treatment groups compared with migraine model groups(P<0 .05) .CCK mRNA expression was significantly lower in midbrains of rats in the Duliang capsule control groups compared with normal control groups(P<0 .05) . Conclusion Duliang capsule can exhibit the expression of CGRP and CCK in the midbrain of the migraine rats .weaken the CGRP and CCK‐induced inhibition of the analgesic effects of opioid peptides .

Objective:To eastablish the efficient presentation of antigen from apoptotic cells by human DC from peripheral blood. Methods: using recombinant human granulocyte/macrophage colonystimulating factor(GM- CSF) and interleukin 4 (IL- 4 ) we have established dendritic cells (DC)from peripheral blood monocyte that maintain the antigen capturing and processing capacity characteristic of immature dendritic cells in vivo. GM - CSF 50ng/ml , IL- 41 000ng/ml once two days(total four). on the 3 rd day of culture, immature DC and apoptotic hepatochlangioma cells were in coculture lasting 7 days. Results:these cells had typical dendritic morphology, express high levels of CD1a ,B7 and acquired antigen from apoptotic cells and induced an increased T cell stimulatory capacity in MLR. Conclusions:we have established DC from blood mononuclear tells using GM- CSF and IL- 4 and DC can be efficiently drived from apoptotic cells and can induce the increase of T cells obviously. It probably becomes an effective approach of antigen transduced with DC.

Objective To evaluate the application of chromogranin A (CgA) as a marker in the diagnosis of prostate cancer. Methods Serum chromogranin A were detected by means of ELISA technique in 35 cases of prostate carcinoma,10 cases of benign prostate hyperplasia and 30 cases of healthy subjects. Results Serum CgA [(162?12.5)ng/ml] of patients with prostatic carcinoma was significantly higher than those of healthy subjects and of BPH( P

Clinical pharmaceutical services include: rounds by clinical pharmacists, monitoring of dynamics and adverse effects of drugs, pharmaceutical information services and analyses on use of drugs. Considering the difficulties that clinical pharmacists have encountered in clinical pharmaceutical services like ward rounds and different clinical knowledge structures, corresponding measures have been taken to assess the work load of clinical pharmacists so as to bring into full play the role of clinical pharmacists in clinical pharmaceutical treatment and information services.

Objective To investigate the diagnostic value and feasibility of PTC diagnosis on pancreaticobiliary maljunction (IBM), and to summarize the PTC radiological characteristics of PBM. Methods Clinical findings and cholangiopancreatographic results were analyzed retrospectively for a group of consecutive 363 patients with obstructive jaundice receiving the PTCD therapy. Meanwhile the standard selected for cases and diagnostic conditions were established. The length and diameter of pancreaticobiliary common duct, the diameter of pancreatic duct and common bile duct and the confluence angle were measured respectively. The t test and rank sum test were used to analyze the result statistically. Results Thirty-eight cases were radiologicaUy diagnosed as PBM owing to the reference standard and the detection rate was 10.5% (38/363). The length of common duct was (12.6±7.9)mm. The significant difference existed between it and normal value (6ram) (t=5.15 , P <0.05). The site of duodenal papilla had influence on the length of common duct. The diameter of common bile duct, pancreatic duct and common duct near the confluence are (3.7±1.9 ) mm, (2.4±1.3) mm, (3.3±1.4 ) mm, respectively. There was no statistical difference between them and the normal value (t=1.79,2.85,5.72, P>0.05). Fifteen patients' duodenal papilla located the middle of descending duodenum. The length of common duct was (10.6±9.1)mm , the confluence angle was 51.1°±28.0°, the number of the duodenal papilla locating in the inferior 1/3 of descending duodenum, juncture , horizontal part of duodenum was 10, 8,5, respectively. The length of common duet were (9.9±3.7), ( 18.6±8.9), ( 13.9±3.5 ) mm, respectively. The confluence angle were 54.0°±18.6°、48.7°±12.6°、74.4°±18.5°, respectively . The site of duodenal papilla had significant influence on the length of common duct(X2=14.51, P <0.05). Conclusion PTC is a safe, feasible, method to diagnose PBM, and it demonstrates the characteristic findings of PBM.

Objective To investigate the neonatal death causes and the relationship between the causes and the neonatal age,fetus age and the year in order to reduce neonatal mortality.Methods Data of neonatal autopsy and pathological records from 107 neonates in our hospital from January 1998 to May 2008 were collected,analyzed and summarized.Results 40.2%of the cases died within 24 hours and 72.9%died within 7 days after birth.The main death cause for those who died within 7 days was asphyxia(48.6%),and the main death causes ior those who died after 7 days were deformity(34.5%)and hemorrhage(34.5%).The most common death cause for premature bahies Was hyaline membrane disease(29.7%),and the most common one for term infants was congenital heart disease(23.3%).In the past 5 years.asphyxia Was still the most common death causein our country,those who died of infection were on the rise and the deformed babies increased too;on the contrary.those who died of obstetric causes and hemorrhage decreased.Conclusion Neonatal mortality could be reduced by prenatal management,prevention of premature delivery,improvement of the cooperation between pediatrics and obstetrics,and better management of NICU.
